The thing is my database is correctly configured, because I get the table role and user_role. However user does not get generate in my postgresql db. My implementation of my autogenerated user domain object looks like that:

class User {

    transient springSecurityService

    String username
    String password
    boolean enabled = true
    boolean accountExpired
    boolean accountLocked
    boolean passwordExpired

    static transients = ['springSecurityService']

    static constraints = {
        username blank: false, unique: true
        password blank: false
    }

    static mapping = {
        password column: '`password`'
    }

    Set<Role> getAuthorities() {
        UserRole.findAllByUser(this).collect { it.role } as Set
    }

    def beforeInsert() {
        encodePassword()
    }

    def beforeUpdate() {
        if (isDirty('password')) {
            encodePassword()
        }
    }

    protected void encodePassword() {
        password = springSecurityService.encodePassword(password)
    }
}

I appreciate your answer!

Answer 1

'user' is a reserved name in Postgres. You can avoid this by setting up a mapping in your domain class and use an alternate name.

 static mapping = { table 'myusers' }

This way your domain class remains the same. You could also escape the name similar to the way you have done with 'password'.
